Vintage Wayne Kerr Universal Bridge B221A Electrical Testing Equipment

The Wayne Kerr B-221 Vintage Universal Bridge is a highly specialized piece of test equipment, designed for measuring electrical components such as resistance (R), capacitance (C), and inductance (L). Built around the 1960s, this device was widely used in labs and industries for precise RLC measurements. The B-221 model can measure resistances from 9 ohms to 50 megaohms, capacitances from 1 pF to 11.1 µF, and inductances ranging from 0.9 mH to 10,000 H, with an impressive accuracy of 0.1%.

Key Features:

• Measurement Ranges: Resistance (9 Ω - 50 MΩ), Capacitance (1 pF - 11.1 µF), and Inductance (0.9 mH - 10,000 H).
• Accuracy: 0.1% for high precision in electrical component analysis.
• Tubes/Valves: Contains 6 tubes, including ECC82, EF91, and EM34, used for signal processing.
• Power Supply: Operates on 100-125V or 200-250V AC.
• Build: Features a durable metal case with dimensions of 430 x 290 x 190 mm and weighs around 24 lbs.
